Code P116E 2016 Chevrolet Silverado Description
The P116E diagnostic trouble code (DTC) on a 2016 Chevrolet Silverado specifically refers to an issue with the O2 Pump Current Control Circuit Low Voltage related to the NOx Sensor 1. This code indicates that there is a problem with the electrical circuit responsible for controlling the current to the O2 pump, which is crucial for the proper functioning of the NOx sensor. The NOx sensor plays a vital role in monitoring and regulating the levels of nitrogen oxides in the exhaust gases emitted by the vehicle.
Common Causes of P116E 2016 Chevrolet Silverado
- Faulty Wiring: Damaged or corroded wiring connections can disrupt the electrical signals necessary for the O2 pump current control circuit.
- Malfunctioning O2 Pump: A defective O2 pump can lead to low voltage in the circuit, triggering this code.
- Defective NOx Sensor: A malfunctioning NOx sensor can also cause issues with the O2 pump current control circuit.
- ECM Malfunction: Problems with the engine control module (ECM) can interfere with the proper functioning of the NOx sensor and O2 pump.
Symptoms of P116E 2016 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A decrease in fuel efficiency may be noticed due to improper combustion processes caused by the malfunctioning NOx sensor.
- Emission Issues: The vehicle may fail emissions tests or emit higher levels of pollutants due to the malfunctioning O2 pump current control circuit.
- Rough Idle: The engine may experience rough idling or hesitation during acceleration as a result of the issue.
How to Fix P116E 2016 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific trouble code and perform further testing to identify the exact cause of the problem.
- Inspect Wiring: Check the wiring harness for any damage, corrosion, or loose connections. Repair or replace any faulty wiring as needed.
- Test O2 Pump: Test the O2 pump to ensure it is functioning correctly. Replace the pump if it is found to be defective.
- Check NOx Sensor: Verify the operation of the NOx sensor and replace it if necessary.
- Clear Codes: After completing the repairs, clear the trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P116E 2016 Chevrolet Silverado
The typical repair costs for addressing a P116E code on a 2016 Chevrolet Silverado can vary depending on the specific cause of the issue. On average, the parts required for this repair, such as a new O2 pump or NOx sensor, can range from $200 to $500. Labor costs at auto repair shops typically range from $80 to $150 per hour, and the total repair bill could amount to $300 to $800 or more, including parts and labor.
